SPECIFICATION forming part of Letters Patent No. 729,457, dated May'k26, 1903. Application tiled June 19, 1902. Serial No. 112,266. (Nomodel.)

To all whom it may concern:

Be it known that I, FRANZ X. WAGNER, a citizen ofjthe United States,residing in the borough of Manhattan, city,county, and State 5 of NewYork, have invented certain new and useful Improvements in TabulatiugDevices for Type-Writing Machines. of which the following is aspecification.

My invention relates to tabulating devices 1o for typewriting-machines,and has for its object to provide an improved mechanism of this classwhich will comprise means for braking the carriageiand which will alsobeso constructed as to be capable of use with an x 5 exchangeable feedmechanism.

To this end my invention'consists of certain features of constructionand combination of parts, as will be fully described hereinafter andthen pointed outin the appended claims.

zo Reference is tobe had to the accompanying drawings, in which- YFigure 1 is a Vrear view of a portion of a typewriting machine having myimprovement applied thereto. Fig. 2 is a cross-sec- 2 5 tional elevationon the line 2 2 of Fig. 1. Fig.

3 is a detail sectional elevation'of the tabulating-stop on line 3 3 ofFig. 1; and Fig. 4 is a similar view on line 4 4 of Fig. 1.

The framing `of the machine is designated 3o asl, and 2 is the fronttrack, on Whichgare` adapted to travel rollers 3, secured to the frontportion 4 of the carriage. The rear portion 5 of the carriage isprovided with a rod 6, adapted to travel on rollers 7, carried byithe35- frame l. The two sections of the carriage are vconnected by apivotal joint 8 in a wellknown manner, so that the platen 9 and the.parts connected therewith may be swung into an upper position. The shelfover whichthe 4o paper passes to the platen is indicated at 10, and 11is a guide-roller. 12 is the ordinary scale located at the front portionof the fca'r-v riade.

'Il-Bhe tabulating mechanism comprises a key 45 13, secured to lever 14,which is pivoted upon the frame at 15. With the rear end of the lever 14is pivotally connected at 16 a crankarm 17. This crank-arm is connectedwith a rock-shaft 18, which extends at right anglesto said crank-arm,and is provided at its other end with a second crank-arm 19, projectingoutwardly from the shaft and slotted atits upper end, as indicated at20. Within the slot of the crank-arm 19 is contained a pin 21, mountedupon an arm 22, which de- 55 pends from a rack-support 23.- There is onerack-support at each end of the machine; but only one of them has theextension or arm 22. These supports are mounted to turn about an axiswhich is indicated by the center of a rod 24v extending lengthwise ofthe machine. The supports may either turn upon the rod or l they may berigid therewith. Bearings 25 are provided at the ends of the machineupon brackets 26,'and these bearings engage the 65 ends of the rod 24.Thearms 23'are connected by or support at their upper portions a rack27, having teeth upon its lower sursurface. The upper edge of the rackis prok.vided with a suitable scale 28, with which 7o the tabulatingstop or `stops 29 cooperate. I have illustrated but one ofthesetabulatingstops, although it shouldv be understood that any suitablelnumber of, such stops may be provided. The stop 29 comprises a casing75 upon which the various parts thereof are "mounted, audthis casing-isperforated, so ythat 'it may slide lengthwise on the rod 24. `A latchor, locking implement 30 is adapted to move' around the rod '24 `-as a8o f-pivot, and a nose or projection 31 on the said latch is adapted tobe received between the teeth of the rack27 when the latchis in theposition indicated in Fig. 4. To facilitate this movement of the latch,atinger-piece 32 85 is provided, which extends through'an opening 33 inthe casing. To the Acasing of the 4'stop is pivoted at 34 an index orpointer 35. A spring 36 enables -the pointer to be moved to'either oftwo positions and tofbe retained 9c in either one of them. When thepointer is in the position indicatedv in Fig. 4, its nose or projection37 will extend over the scale 28,

so as to determine the proper positioning of the stop. When the latch 30is locked in the 95 manner indicated in Fig. 4, the stop will be lockedon the rack 27, so as to prevent a movement of the stop lengthwise ofthe rod 24. A spring 38 coperates with the latch 30 and tends tonormally force the latch into the locking position shown in Fig. 4. Inorder,

however, to keep the latch in the unlocked' position when desired, aprojection 39 is located at one side of the casing. (See Fig. 3.) Thisprojection is adapted when the latch 30 is in the unlocked position toproject into a depression 40 on the latch, and thus to maintain thelatchagainst movement bythe spring 38. When, however, the inger-piece 32 ismoved by hand, the pressure is suiiicient to force the projection 39 outof the depression 40, thus permitting the latch 30 to be moved to theposition indicated in Fig. 4. Thelatch 30 performs a twofold function.When the tabulating-key is depressed, the tabulatingstop 29 in itsentirety will be moved in the direction of the arrow in Fig. 2, thusbringing the front face of the spring-pressed latch 30 into contact witha longitudinally-extending portion 4l on the carriage-frame member 42.This will exert the braking action on the carriage, so as to retard itsmovement when it has been released by the tabulating-key. The pressureof the latch 30 against the part 4l is, however, not sufficient torelease the projection 3l from engagement with the rack` 27. Thisdisengagement can be effected only by hand, preferably by a movement ofthe hand operated finger-piece 32. The tabulatingstop, it will beunderstood, cooperates with a suitable projection or stop 5 on thecarriage to arrest the latter at the position for which the adjustablestop 29 has been set.

On the key-lever 14 at its rear end is secured a screw 43, which fitsinto a bifurcated portion 44 at the lower end of a link 45, the upperend of which is pivotally connected with a lever 4G, fulcrumed at 47upon a bracket 48, fixed to the frame of the machine. This lever isadapted to engage a pin 49 upon the feed-dog 50, which is movableverticallythat is, in a direction at right angles to the direction offeed. This feed-dog in its downward movement is arranged to carry alongwith it the other feed-dog 51, so as to release both dogs from the rack52 on the carriage. The mechanism by which one dog is thrownlongitudinally of the rack when disengaged therefrom and the mechanismfor operating the dogs to produce a feed whenever a typelever isoperated form no part of my invention and may be of any approvedconstruction. In the construction shown the feeddogs are carried by ashaft 53, mounted to rock by the means of any suitable mechanism., suchas the crank-arm 54 and operating-lever 55, worked from the universalbar or in any other suitable manner. This shaft is mounted to oscillateupon cone-bearings 56 57. The cone-bearing 57 is in the form of a pin,which is adjustably secured in a fixed portion of the framing of themachine by the screw 58, while the bearing 56 is formed by the end ofthe longitudinally-movable rod 59, which is normally maintained in. theinner position by a spring 60, one end of which bears against thebracket 48 and the other against a sleev'e 61,secured to said rod 59.This rod is guided in brackets 48 and 62 and is'provided at its outerend with a finger-piece 63, by means of which it may be withdrawn, so asto permit the shaft 53 and the parts carried thereby to be removed fromthe machine.

The operation described in detail is as follows: A depression of thetabulating-key 13 will cause the inner or rear end of said key to moveupward, thus causing the shaft 18 to rock by reason of the connection 16between the tabulating-key lever and the arm 17 on the rock-shaft. Therocking of the shaft will effect a rearward movement of the upper end ofthe crank-arm 19, thus swinging the rack 27 and tabulatingstop or stops29, carried thereby, toward the carriage-that is, in the directionindicated by the arrow in Fig. 2. This movement will, as hereinbeforedescribed, bring the latch 30 against the longitudinal portion 41 of thecarriage-frame, so as to produce a braking action when the carriage isreleased, and at the same time the tabulatng-stop 29 is brought into thepath of the corresponding stop upon the carriage. The initial movementor depression of the tabulating-key 13 will cause the inner end of thelever 14 to rise without lifting the link 45, the screw 43 movingloosely between the members of the fork 44. Thus the tabulating-stop andthe brake will be brought into the operative position before the link isoperated. The further movement of the tabulating-key 13 will cause thelink 45 to be raised, since the screw 43 abuts against the upper wall ofthe slot, and thus the free end of the lever 46 will be depressed,disengaging both feed-dogs from the feed-rack, so as to release thecarriage. When the said key is allowed to return toits normal position,the tabula'ting-key lever 14 and the link 45 will resume the samepositions with relation to one another which they did before thedepression of the key by reason of the loose connection 43 44 betweenthe said parts.

While I have shown with considerable detail one specific embodiment ofmyinvention, it should be understood that the arrangement and detailconstruction of the several parts may be varied considerably withoutdeparting from the nature of my invention.

What I claim as new, and desire to secure by Letters Patent, is-

1. In a type-writing machine, the combination of a carriage, feedmechanism therefor, a stop carried by said carriage, a coperating stopon the framing of the machine and which is normally out of the path ofthe stop on the carriage, key-operated-means for moving one of saidstops into the path of the other, means for disconnecting thecarriage-feed mechanism to free the carriage when the key-operated meansfor the stop are actuated, said dis- IOO IIO

connecting means comprising loose connections whereby a movement ofcertain of the parts may be effected independently of others.

2. In a type-writing machine, the combinaspring-pressed meanscoperates,`one of said lastmentioned parts being adapted to be forcedinto contact with the other when the key-operated mechanism is actuatedso as to retard the free movement of the carriage when it is released.

3. In a type-Writing machine, the combination of a carriage, feedmechanism therefor, a tabulating-stop which cooperates with and isnormally out of the path of a second stop, key-operated mechanism foroperating the tabulating-stop and releasing the feed mechanism to freethe carriage, a spring-pressed abutment carried by saidtabulating-stop,and a bearing-surface with which said springpressedabutment cooperates, said springpressed abutment being adapted to beforced into contact with the bearing-surface when the key-operatedmechanism is actuated so as to retard the free movement of the carriagewhen it is released.

4. In a type-writing machine, the combination of a carriage, feedmechanism therefor, an adjustable tabulating-stop which coperates withand is normally out of the path of a second stop, a scale with whichsaid tabulating-stop coperates, key-operated mechanism for forcing thetabulating-stop into the path of its coperatng stop and for releasingthe feed mechanism to free the carriage, a springpressed abutmentcarried by the said tabulating-stop, and a bearing-surface with whichsaid spring-pressed abutment coperates,said spring-pressed abutmentbeing adapted to be forced into contact with the bearing-surface whenthe key-operated mechanism is actuated so as to retard the free movementof the carriage when it is released.

5. In a type-writing machine, the combination of a carriage, feedmechanism therefor, an adjustable tabulating-stop which coperates withand is normally out of the path of a second stop, a scale with whichsaid tabulating-stop cooperates, key-operated mechanism for forcing thetabulating-stop into the path of its cooperating stop and for releasingthe feed mechanism to free the carriage, a springabutment carried bysaid tabulatingstop, hand-operated means for moving the springpressedabutment to render it inoperative as such, a locking-abutment which islikewise controlled by said hand-operated means to lock the stop in itsadjusted position, and a bearing-surface with which said springpressedabutment cooperates, said springpressed abutment being adapted to beforced into contact with the bearing-surface when the key-operatedmechanism is actuated so as to retard the free movement of the carriagewhen it is released.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
